To all whom z'tmay concern: 7

Be itknown that I, QHARLEs E. REDDIG, a citizen of the United States, residing at Kew Gardens, Richmond Hill, in tlie oounty of Queens, State of New Yoirlglmve invented certain new and useful improvements in Prime Mover Dynamo Plants, of i'vliich the following is a full, clear, concise, and exact description;

This invention. relates to prime mover dy name plants, and partieulai'ly to such plants employing an internal combustion engine to drive a generator used for charging a storage battery.

its primary object is to regulate automate ically the output of the generator so as to secure a tapering charge for the battery.

In accordance with the general features of the invention there are }TOVll%d means for controlling the power output 0f the (ly name in accordance with the amount of fuel. in the fuel supply tank of the engine, and auxiliary means to overcome the ell'ect of the fuel eontmlled means when an excess load is inserted in the generator circuit.

The drawing is elevation pit. 'ially in. section showing one embodiment of, the in ventien. I

shown in the drawing, an internal tom; liustion engine 5' operates (l 222K110 electrie connected to thereoi A battery 16 and e load 11., sue: as electric lamps. are inserted. across leadsfi A switch 12 is pro-- vided. for cutting the load 11 into or out of the circuit The crank shaft 1.3 of the en gine is geared to cam sheila 14- upon which an ignitidri tim ng mechanism 1.5 is rotatably mounted Biflie exit-5i is f to'vided with a fuel titnk it'll holding pielfetalily an amount of fuel very slightly in excess 015 that rel uii'ed completely charge the bet terya y the use of this feature a slight overcharge may be L l; any execssive overcharge is effectually if 'evented. In the will: is a float i'i'uttacheci a iQVQY 18 pivotecl at 19 to one side of the tank" Ai tecli zrlto lever 18 is a vertical bar having at its upper eml a horizontal between the prongs of which pin projecting from the timer l5.

, As the level 01? the fuel. in. the tank is low ered', the float 17' drops, lowering the lever- 18 and the horizontal bar 20 thereby rotatleg the ignition timer mechanism-'15; in it machine 7 liming leads anti $1 the termir a supplies t elockwise direction te retard the spark and reduce the speecl of the engine This reducxes the Fewer output of the generawr and 1e desired tapering charge to the battery ll). v

If it is desired to eonneettlie load 1.1 into the circuit during the elwrgii'ig of the sl m age battery, a load responsive solenoid operating e plunger 26, fox-"med about, at otherwise attached to, bfill." 2% is inserted into lead 9.. Uponthe insertion of a lead into the circuit, this solenoid will be eizergizeel, lifting plunger 25 and be: EEG- and rotating the timer T15 in a count-e eioeleii'ise tlireetieir to overcome any rotation of the timet oaueerl by a drop in the height; of the fuel tlr tank 16. this mam-m? the timer may be regulated to adjust the the to any sized load.

It will e'vioient that ignition time: control meanemey lie by valve control mem'ie and t-bet other may be made in the rippaietue Wi emit parting from the spirit of the invent The invention elitimeci is:

1. In combination, an eng ne ope-w liquid fuel a fuel. m1; will:

6. In combination an internal combustion en ine, generator driven thereby, a stora "e battery charged by the generator, 2. fuel sup y tank forthe engine to hold substanenough fuel to charge the storage batnl means responsive to the height of in the tank to so regulate the give tapering ch21 to the battery.

7. .ln a prime mover dynamo plant, an internal combustion engine, a dynamo electric machine driven tnereby, a load circuit for the dynamo electric machine, a storage battery and a "variable load connected across said circuit, a fuel supply tank for the engins, means to slowlv decrease the speed of the engine as the able load for overcoming the effect of the first mentioned. means.

3. ln combination internal combustion engine comprising a cam shalt, a fuel sup- ;Jl tank for the engine, a float in said tank, an ignition timing mechanism rotatively n'iounted. upon said cam shaft, and bar and lever members connecting the float and the timing; mechanism so that as the float is lowered the ti ng mechanism will he rotat 3 I I ruei in the tank is exhausted, and means responsive to said varithe float is lowered the timing mechanism will be rotated to retard the spark and reduce the speed of the engine,

10. In a prime mover dynamo plant, an internal combustion engine, speed control means for the engine, a dynamo electric ma.- chine driven by the. engine, a load circuit for the dynamo electric machine, a storage battery and a variable load connected across said circuit, a fuel supply tank for the engine, a float in said tank, means connected with said lloat for actuating said speed control means, and GlQCJIlCBl means operating in conjunction with the last mentioned means to overcome the effect of the float upon said speed control means.

11. In a prime mover dynamo plant, on internal combustion engine, a dynamo electric machine driven thereby, a load circuit for the dynamo electric machine, a storage battery and a variable load connected across said circuit, a cam shaft on said engine, an ignition timer rotatably mounted on the cam shaft, a fuelsupply tank tor-the engine, a lever in the tank pivoted to one side thereof, a float at the end of said lover, a bar for connecting the lever with the timer so that as the float is lowered the timer will he rotated to retard the spark and reduce the speed of the engine, a portion of said lmr being formed of magnetic material. load responsive solenoid connected in said circuit and formed about said magnetic portion of the bar which acts as a plunger. so that y the encrgization of the solenoid the efect of the lowering of the fuel in tank will overcome when an increase inthc speed the is necessary to carrv the load. In Witness whereof, I hereunto subscribe my name this 13th day of November A. l). 1922.
